This invention relates to improvements in work-tables, such as power-tables, cuttingtables and the like, and has for its object to provide simplified means" for securing the table-top or top-boards upon supporting standards, and more particularly for securing abutting sections of said top-boards upon the standards.

The invention consists in the'devices, combinations and arrangement of parts herein- This application is, in part, a continuation of my prior patent application Serial No.

In the accompanying drawing, Fig. 1 is a front side elevation, partly in section, of a portionof a work-table having top-boards secured by an'improved top-board clamping device. F ig. 2' is an end View of a portion of the cutting-table. Fig. 3'is aside elevation, partly in section, ofa modified. arrangement'for clamping the top-boards of a table upon a supporting standard. r

As represented in the drawing, the. cutting-table has a table-top supporting structure including vertically adjustable legs 1 and '2 constituting standards supporting channel-bar rails 3 and 4 which, in the preterred embodiment of theinvention, are of inverted U-shape and are disposed crosswise of top-boards 5 and 6. The top-board 5 is an end board of'the table,overlying the end rail 3 and resting'upon a portion'of the intermediate rail 4: which also supports one endor" the top-board 6 in abutting relation with the end-board 5. i The other extremity of the top-board 6. may overlie anend rail in a. manner similar to the overlying relation of the board 5 with respect to the'rail 3, to thereby constitute an end-board, or it may be disposed in abutting relation with V the top-board 5 at opposite sides of theendstill anothertop-board, dependent upon the desired length of the table. 7 1 Referring more particularly to Figs. 1 and 2 of the drawing, to the under face of railS, .and to the under faces of the abutting extremities of the top-boardsb and 6 at opposite sides of the intermediate rail 4, are secured substantially*U-shaped angle jacent opposite sides of a rail are conver- ..er sides of the rail at a downward: inclinathe a drawin 1932.

The bolts 10 directly adgently inclined downwardly to engage therail therebetween at the lower edges of the rail, said bolts passing through suitable apertures provided directly below the lower edges of the rail ina channeled'clamp-member 13 having upturned side fianges, held by the bolt-heads 14' against the lower edges of the rail. Each clamp-member 13 is bent upwardly between its en'dj'sto' provide boltengaged portions extending beyond the outtion and in substantially parallel relation tive an leebrackets .connected' therewith.

The. described construction constitutes a very powerful table-top; clamping expedient,

whereby the adjacent extremities of the boards 5 and 6. may not only be drawn downwardly upon therail but also drawn toward each other, into closely abutting relation. In fact, the described expedient provides for straightening warpedtop-boards,-

and is therefore also useful for securing'the extremity 01 a board overlying an end rail 3.

Nevertheless, the device is of simple constructiom nay be manufacturedat low cost-- and provides tor ready shipment andinstallation of a table equipment.

each apertured to receive the hooked upper extremity of a turn-buckle section 19 threaded into a collar 20 adjustably connecting said section 19 with a similar section 21 of which the lower end is correspondingly hooked. The hooked ends of the turnbuckle sections 21 enter suitable apertures provided in a channeled clamp-member 22 having turned up side flanges 23 which are suitably recessed to receive the lower edges of the'rail 4:. As in the case of thebolts 10, by tightening the downwardly-converging turn-buckles the adjacent extremities of the table-top boards are not only firmly secured upon the rail 4, but are also drawn into closely abutting relation.

Having thussetforth the nature of the invention, what I c1aimhei'ein'is:-
